Does your presentation have a title? I'd use it here rather than the conference title if it does.Also - Arial in blue isn't working for me. I'd go with Verdana or Trebuchet, and use colours from the Intute website - I've used a few examples on the slides :). But then....I do get overly preoccupied with fonts!Also - be consistent with your layouts. Do you have a master set up?

Really like this slide - nice image. I would be inclined to have the image as the hyperlink so you click on the 'answer' and the demo appears.
